A charge of 5 C is moved between two points in an electric field and 20 J of work was done to do so. Calculate the potential difference between the two points

Seven capacitors, each of capacitance $$2\mu F$$ are to be connected to obtain a capacitance of $$10/11\mu F$$. Which of the following combinations is possible?

Two identical capacitors are joined in parallel and charged to a potential V. Then these are separated and connected in series with the positive plate of one connected to the negative ofthe other. Then the

Three capacitors each of 1 microfarad are connected as shown below, The capacitance between the points $$A$$ and $$B$$ is :

$$ECG$$ is a method of diagnosis used to check the functioning of heart, it is based on the principle that there is

1 V equals :

What is the resultant capacitance between points A and B?

The electric potential at the surface of an atomic nucleus (Z = 50) of radius $$9.0 \times 10^{-13} cm$$ is:

In the circuit shown in the figure, the potential difference across the $$4.5 \mu F$$ capacitor is:

Minimum numbers of $$\displaystyle 8\mu F$$ and 250 V capacitors  are used to make a combination of $$\displaystyle 16\mu F$$ and 1000 V are:
